System Schematic For Alarm Module (ALM)The alarm module (ALM) is available as an option. The alarm module may be mounted on the front panel. Also, the alarm module may be placed at a distance from the control panel as a remote annunciator. The alarm module is used in order to satisfy the requirements of the customer. The alarm module may be used in order to satisfy National Fire Protection Association (NFPA) requirements by annunciating the presence of a fault.The ALM communicates with the GSC+ by a serial data link. When the data link malfunctions, all of the indicators on the ALM, that are controlled by the data link, flash at a rate of .5 Hz.Note: The maximum number of the ALM or the Customer Interface Module (CIM) that may be connected to the serial data link is equal to three. The maximum distance between a module and the GSC+ is 305 m (1000 ft). If these specifications are not met, the ALM indicators may begin to flash. The GSC+ shows a CID 333 fault. If the setup is not in compliance with the specifications, reduce the number of modules and/or shorten the distance to the modules.Note: Faults are created when the harness connector is disconnected from the GSC+ during these troubleshooting procedures. Clear these created faults after the particular fault is corrected and the particular fault is cleared. In a properly operating system, when the harness connector is removed from the GSC+, the diagnostic fault codes that are listed below are recorded.CID 100 FMI 2 - Pressure Sensor (Engine Oil) CID 110 FMI 2 - Temperature Sensor (Engine Coolant)CID 111 FMI 3 - Fluid Level Sensor (Engine Coolant)CID 175 FMI 3 - Temperature Sensor (Engine Oil)CID 190 FMI 3 - Speed Sensor (Engine)CID 336 FMI 2 - Switch (Engine Control)CID 590 FMI 9 - Engine (ECM)The possible cause of a CID 333 FMI 3 fault is a short to "B+".The GSC+ treats a CID 333 FMI 3 fault as an alarm fault. Clear the fault from the fault log after troubleshooting is complete.Note: If a CID 333 FMI 3 fault is showing on the upper display and no alarm module is installed, then check the terminal strips on the subpanel for a short. Perform the check from the signal wire to "B+". Check the customer connection box for a short from the alarm data signal wire to "B+".
Check The Status Of The Fault.
Turn the engine control switch (ECS) to OFF/RESET and then turn the ECS to STOP.
Press the "Alarm Codes" key.
Observe the upper display for a CID 333 FMI 3. The fault is active if the upper display shows a CID 333 FMI 3.
If the fault is not showing, enter the service mode and view the fault log (OP1). Check the upper display if the fault is showing.Expected Result: A CID 333 FMI 3 fault is active or inactive.Results:
OK: A CID 333 FMI 3 fault is active. Proceed to Step 2.
OK: A CID 333 FMI 3 fault
